This report presents the development of a device for removal of inorganic salts from drinking water to facilitate the subsequent concentration of organic solutes for bioassay. Prior attempts to concentrate the organic solutes by reverse osmosis (RO) resulted in precipitation of the inorganic salts. To prevent this precipitation, the drinking water is pretreated by Electro-Regenerated Ion-exchange Deionization (ERID). The ERID device developed for this purpose is essentially an electrodialyzer with thick depleting compartments packed with a mixture of anion- and cation-exchange resin beads. The resins provide a conductive medium for electrical transport of ions out of the demineralized water, through ion-exchange membranes, and into a concentrated waste stream.
